[NMF-user] Loading NMF fails when in a container

[Roel Janssen]

Hello there.

First of all, thanks for creating this package.  It's really useful.
I've been trying to confine run-time environments in a container (so the
program only has access to a subset of the operating system).

When loading NMF from inside a container, it fails and I don't know what
I'm missing.  Here's the output from inside the container:

---------------------------------- BEGIN ----------------------------------

I couldn't find 'if (n > 2) n <- n - 1L' in the source code, so I am
clueless on what goes wrong here.

Any ideas?

Kind regards,
